Description

The invention relates to the field of marine engineering, in particular to marine autonomous power supply devices designed to study the world's oceans at various depths.

The closest in technical essence to the claimed invention is an Inertial-piston wave power plant (RU 2388933 dated 05/10/2010), containing a buoy, an autonomous electric source and a rechargeable energy device with a mechanism for connecting it to this source, an inertial piston made with the possibility of return - translational movement up and down due to vertical movements of the buoy under the influence of fluctuations of the water surface and spring shock absorbers, while the output of the rechargeable energy the device through the connection mechanism is connected to the input of an autonomous electric source, the installation is equipped with an air turbine, such as a Wells turbine, and air tubes, and an autonomous electric source made in the form of a capacitive molecular energy storage device based on a two-layer capacitor, and a charging device including a DC generator with a voltage regulating relay, the rotor of which is rigidly connected to the turbine blade wheel, and a rotation mechanism with air a cylindrical-shaped ear container, inside which an inertial piston is attached, mounted on the top and bottom inside the container body using spring shock absorbers, while holes are made in the lower and upper parts of the container to which air tubes are rigidly attached, the arrangement of which ensures air flow to the wheel blades turbines caused by oscillatory reciprocating movements of the inertial piston.

The disadvantage of this device is the need for exposure to vibrational movements of sea waves for the inertial-piston wave power plant, especially in difficult ice conditions.

The objective of the invention is the creation of a power plant for long-term autonomous power supply of marine devices in areas with difficult ice conditions.

The required technical result is achieved by the fact that the buoy, equipped with a control unit and communication and navigation modules, having an autonomous electric source and an electric generator, the rotor-electric generator is rigidly connected to the impeller, and the electric generator is placed in a hollow vertical cylindrical body, having an extension in the lower and upper parts; on the outer side at the top of the casing there is an air tank with a control valve, in the lower part of the casing there is a sealed cylinder equipped with a shut-off valve and a hydraulic pump; the case is equipped with upper and lower limit switches and is freely attached to the buoyrp; a buoyer connects the buoy with a unit of an autonomous electric source and electronic modules of detection equipment; an electric cable is laid inside the buierep, connecting the unit of an autonomous electric source with electric consumers of a buoy; the electric generator is connected by a cable to a unit of an autonomous electric source through a reeling device.

The invention is illustrated by drawings, where in FIG. 1 shows a diagram of a device of a power plant for autonomous power supply of marine devices in areas with difficult ice conditions, which contains:

1 - control unit and communication and navigation modules;

2 - buoy;

3 - fastenings to the buoyrp of the body of the power plant;

4 - power plant building;

5 - locking devices;

6 - buirp;

7 - autonomous electrical source.

In FIG. 2 shows a diagram of a device of a vertical cylindrical body of a power plant, which contains:

8 - air capacity;

9 - upper limit switch;

10 - control valve;

11 - impeller wheels;

12 - electric generator;

13 - sealed container;

14 - lower limit switch;

15 - hydraulic pump;

16 - locking valve.

A power plant for autonomous power supply of marine devices in areas with difficult ice conditions works as follows: before setting up, the device is prepared, the optimal installation depth of the detection devices is determined, i.e. the length of the buoyer, and locking devices (5) are set and zero buoyancy of the power plant building (4) is regulated by filling or bleeding air from the air tank (8) through the control valve (10) with a sealed cylinder half filled with water (13).

The operation of the device begins with filling a sealed container (13) with water through a shut-off valve (16), the buoyancy becomes negative, and the body of the power plant (4) begins to sink. When moving along the buoyrup (6), with which it is freely connected through the mount (3), the lower extension of the body (4) compresses the water column and directs it to the impeller wheels (11) of the electric generator (12), forcing them to rotate and generate electric energy then to an autonomous electric source (7) via cable through a rewinder. An autonomous electric source (7) is an electric power accumulator, and incoming electric power is accumulated on it. Having plunged to a predetermined depth when the lower limit switch (14) comes into contact with the locking device (5), the hydraulic pump (15) starts; which produces pumping water from a sealed container (13), which leads to an increase in the buoyancy of the body of the power plant (4), and it pops up. With free ascent, the upper extension of the body compresses the incoming water flow and directs it to the impeller wheels (11) of the electric generator (12), forcing them to rotate and generate electricity, which then comes to an autonomous electric source (7) via a cable through a rewinder. Float to a depth limited by the locking device (5) when the upper limit switch (9) is in contact, the shut-off valve (16) opens, through which the sealed cylinder (13) is filled with water, buoyancy is reduced, and the power plant housing (4) begins to sink. Moving up and down the buoyrup (6), the device allows replenishing electricity in an autonomous electric source (7), which is spent on the detection of underwater targets, the implementation of control, communication and navigation.

The power plant allows you to work autonomously for a long time in difficult conditions. With increasing ice cover, the buoy freezes into ice and drifts with the ice fields, fulfilling its mission on the route in full. Using the control unit and communication and navigation modules, the operator of the control center controls the location of devices, the efficiency of target detection in the area and, if necessary, can organize the setting of additional devices and the evacuation of ineffective ones. The communication module promptly notifies the control center of the detected targets and their characteristics.

The power plant for autonomous power supply of marine devices in areas with difficult ice conditions will find its application in marine areas in the polar regions, and especially in the Arctic seas washing the territory of the Russian Federation.
